I feel your pain about the price increase. WallMart Bamboo kabob sticks used to be $.77 per 100 as soon as I started to use alot of them $1.34 per 100. Every thing else seems to be climbing pricewise also.
I have never tried that paint. Its 115 in the shade here in the summer. But 82 degrees in the dead of winter, nice about 9 mos of the year. I could not get any paint to stick to my coro Regal plastics 3mm and 2mm white. Heat then ac plus glow fuel= peling paint for me. Do you prep the surface ?
